With World Water Week just completed, it’s crucial to recognize the vital importance of the Great Lakes, especially Lake Michigan, to Chicago and the entire region. These lakes provide drinking water for millions of people and sustain local ecosystems and economies worth billions annually.

However, the precious resource of water is under growing threat. Pollution from urban runoff and industrial discharges continues to degrade water quality. Stormwater runoff alone accounts for nearly 80% of the pollution in the lakes, carrying fertilizers, chemicals and trash that threaten aquatic life and water safety. Invasive species such as Asian carp further jeopardize native habitats and fisheries, costing the regional economy billions and risking ecological stability.

Climate change compounds these challenges. Over the last century, water levels have fluctuated dramatically, and increasing storm intensity leads to flooding and water management pressures. Rising temperatures increase the frequency of harmful algal blooms, which can produce toxins that affect wildlife and human health.

The Metropolitan Water Reclamation District is leading the way with innovative solutions, including green infrastructure programs, that are designed to combat these issues. Our Green Infrastructure Partnership Program promotes natural solutions such as rain gardens, bioswales, permeable pavements and green roofs. These initiatives help absorb and filter stormwater at its source, significantly reducing runoff entering Lake Michigan and other waterways.

MWRD investments have shown positive results, reducing combined sewer overflows, improving water quality and creating green spaces that support biodiversity and community well-being. Expanding these efforts in Chicago and across the region is critical. Combining green infrastructure with upgraded wastewater treatment, shoreline habitat restoration and invasive species prevention creates a comprehensive strategy to protect and restore Lake Michigan’s health.

The health of the Great Lakes depends on our commitment now. By expanding green infrastructure initiatives, we can reduce pollution, adapt to climate change and safeguard this vital water resource for future generations. Our shared responsibility is to act decisively. Protecting Lake Michigan means protecting our region’s ecological, economic and community well-being.

Protecting the Great Lakes requires concerted effort. Local governments, environmental organizations, businesses and residents must collaborate to reduce pollution, promote sustainable water use and prevent invasive species from disrupting native habitats. Stormwater management and pollution controls are critical to maintaining water quality. Our actions today will shape the health of the Great Lakes and the future of Chicago tomorrow.

By investing in conservation and sustainable management, we can ensure that these waters continue to sustain us all.

First day of school

Thank you to photojournalist Antonio Perez for the sweet memories in his photos of the first day of school in Chicago Public Schools (“Excitement amid cuts,” Aug. 19). I remember the smiles and joy my children had going to school on the first day.

When I started teaching, my first and second grade students were happy and eager to share their favorite picture book I asked them to bring on the first day. Those books we shared opened the door to learning the joy of reading. Happy reading!

Takeover of extremes

Interesting article about “Christians” and empathy (“Preaching against empathy growing,” in print Aug. 24). This is one of the biggest problems in our country today. The extremes have taken over politics and have taken over religion.

The far right wants to ban everything that they disagree with, while the far left wants to go overboard in supporting their viewpoint.

In discussions, I used to be the devil’s advocate — but now, I can’t do that often because there are such strong viewpoints on each side of a discussion and people will not know I am joking.

Why can we not respect each other and work together to solve problems?

Evolution in mindset

I was delighted to see my fellow parishioner Sara Roemer-Fieberg’s letter in last Saturday’s Tribune (“Shortage of priests,” Aug. 23). With his Chicago connections, do you think Pope Leo XIV gets the paper?

Just in case he hasn’t perused it thoroughly, maybe we should send him a copy.
